Keep in mind the 9700K is only an 8 Core / 8 thread processor. Here on my Windows machine I will choose the "h264_qsv" (Intel Quick Sync Video acceleration) encoder. Mar 6, 2021 · Hello everyone. 264 for the same picture quality (NVIDIA NVENC, Intel Quick Sync video) H264: 31 - 40 MB: Better: Fast: Best codec for most users: H264 (High 4:4:4) 40. 264 is better quality butbuses cpu H. So if you have been, drop that. Of course libx264 is a software encoder while h264_amf is a hardware-accelerated encoder so libx264 InterestingElection2. benchmark. Nvenc vs AMF for recording / encoding in premiere, davinci => AMF looks like Nvenc with the same cqp but will need a higher bitrate. 264 is x264 (CPU encoding) and NVENC (hardware encoding) H. I have bitrates of 3Mbps, 6Mbps, and 8Mbps for 1080p, and 8Mbps, 12Mbps, and 16Mbps for 4K encodes. Moreover, Nvenc accurately renders in-game text, ensuring legibility, while x264 may result in dropped frames and illegible text. Depending on the load on your system at the time, your 970 may or may not produce a better encode using NVENC then your 9700K can pull off. Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '1366_pngl_20220816_161558. Also, until you get into the NVIDIA RTX generation, hardware encoding quality is quite inferior to software. 264 encoder stack) can provide. This generates the output file in MP4 format (output. I did not specify any other options for key frames or the like, as I apparently wrongly assumed ffmpeg would use essentially comparable defaults. 264 if ur cpu cant handle it Nvenc is just nvidias version. 264 (AVC). Entire FFMPEG output is : [h264 @ 000001fb84706c40] Reinit context to 1920x1088, pix_fmt: yuv420p. ext -c:v h264_nvenc -rc constqp -qp 28 output. You can also see all the NVENC-based encoders and NPP-based scalers (if built as such) by running: We would like to show you a description here but the site won’t allow us. NVENC does look cleaner, slightly sharper than X264. 264 da AMD está finalmente quase no mesmo nível dos codecs de vídeo de hardware Nvidia e Apr 3, 2024 · ffmpeg -h encoder=h264_nvenc. That being said. Best OBS Encoders Ranked - 1: (New)NVENC 2: NVENC 3: X264 4: H264/AVC (Advanced Media Framework) - Here's why. Ironically, h. In today's video I compare all of the major streaming encoders - X264 vs NVENC vs AMF/VCE vs AMD has improved their encoding but AMF is still behind Nvenc for streaming quality and Quicksync for offline encodes. • 2 yr. The median encoding latency for an Nvidia card is 5. oi rj uo xs hv cp jv yw by vu
